.Application filed March 29, 1915. Serial No. 17,787.

To all whom t may concern:

Be itknown that I, HENRY P. Hown, a citizen of the United States ofAmerica, and resident of Holyoke, in the countyv of Hampden and State ofMassachusetts, have invented certain new and useful Improvements inPaper Machinery, of which the following is a full, clear, and exactdescription.`

This invention relates to paper machinery to be especially employed inconjunction with a machine, or a portion of a Fourdrinier vpaper machinewhich in the forward feeding of the continuous web cuts the web intosheets and forwardly delivers the latter to form a pile,-the machine oradjunct constituting the present invention having forits purpose notonly to effect the piling of the sheets advanced from the cutter,heretofore in many cases performed by a layboy, but alsoto convenientlyeffect a transferring of the pile, after the same has been sufficientlybuilt up,`to a furtheradvanced position, leaving the place on thesupport at which the paper had been piled free or vacant for the takingon of another pile.

Other objects are attained by the present invention which, with theadvantages thereof, will be hereinafter rendered apparent.

The invention is described in conjunction with the accompanying drawingsand is defined in the claims. f

In the drawings z-Figure 1 is a plan view of the forward portion of asheet cutting machine (or supplement of a paper making or othermachine), which comprises the sheet -advancingand delivery feed tapes,and of the improved` piling and pile transferring mechanism. Fig. 2 is aside elevation of the saine. F ig. Sis a `partial sectional view astaken on line 3 3, Fig. 1, on a somewhat larger scale for clearerillustration of the parts, and the relations of the parts, showntherein.

In the drawings, A represents the forward part of a machine of common,well known,

and extensively used, character for cutting the continuous web coming toand through the same transverselyinto sheets. Included in this machineare roll supported and driven feed tapes a and b, the upper course Vofthe one b having running engagements around the foremost roll d thereforwhich is positioned in proximity to and supportedl by the transversegage bar B included in the present novel mechanism.

Describing the novel mechanism, C repre sents a suitable low framehaving horizontal rotatable shafts f, f2 at the rear and forwardportions thereof, each shaft having opposed pairs g and g2 of toothedwheels affixed thereon.

D represents an endless support or con veyer consisting of transversearticulated flat s lat's, each having in conjunction with its jointingpivot e, and inward projection It, these severally and successivelyhaving engagements with and between the teeth of the sprocket-likewheels g and g2 for acquiring a chain feed action for the slattedconveyer and support which is of a flexible character as apparent. Theedge portions of the support and conveyer D,-at the upper coursethereof, are sustained on ledges z' longitudinally ranging at oppositesides of the frame, whereby such upper course is prevented from sagging,and remains fiat and horizontal.

@ne of the shafts f2 carrying the toothed wheels g2, g2 has means formanually rotating it, such, for instance, as the crank handle f2.

E represents a longitudinally ranging gage board supported by bracketsE2, E2, and extending above a rear end portion of the upper course ofthe jointed slat conveyer and coincident with, or adjacent to, the rearlongitudinal edge of the latter.

The aforementioned transverse gage board B has its location above therear end portion of the conveyer and it is vertically adjustably movablein conjunction with the aforementioned feed tape roll CZ and has meansfor effecting its rising and lowering movements which will be nowdescribed.

On the upright frame extensions C2 at the rear, andupstanding above, theframe proper C are a pair of horizontal transverse shafts G and G2having sprocket chains H H running around the sprocket wheels J and J2which are aiiixed on, and near the opposite ends of, the respectiveshafts Gr and G2.

The forwardly locatedvertical courses of the frame extensions C2.

Any'suitable means are provided for rotating the sets of aforementionedshafts and sprocket wheels for effecting the elevation of the gage boardand the lowering thereof as from time to time is required in making useof my improved mechanism Y 'In the present instance an intermediateshaft L is provided parallel with the shafts G and G?.

On this shaft L is affixed a sprocket wheel 0, shown as outside of theframe extension and above which, on a suitably extended portion of theupper shaft G is a similar sprocket wheel p around which runs a somewhatshorter endless sprocket chain g. The shaft L has the comparativelylarge hand wheel L2 thereon by means of which through the connectionsdescribed the transverse gage bar or board B is operated.

The aforementioned brackets lo 7c carried as rearward extensions of thegage board B form supports for the horizontal shaft t which s affixedtherein and on which the aforementioned forward tape roll cl continuousfor its entire length, or divided into a series of short spools, ismounted.

The aforementioned gage board B also forms the primary support for theyieldable rollers o o which are above and coact with the advancedportions of the feed tape, which round the roll d for preventing thepaper, forwardly moving over andacrossthe gage board, from beingupwardly deflected in any undue extent. As specifically shown,

A these rollers 'v are carried on the free. ends of arms o2 which arehung for rocking movements on a cross rod or shaft o3 sustained by xedarms or brackets 'U4 forming rigid eX- tensions ofthe cross rod t beforementioned as supported on the gage board provided brackets c. Y

The sprocket chain g and sprocket wheels 79 and o are duplicated at therear of the machine, the sprocket chain g2 there shown having acounterbalancing weight w thereon, for preventing when-not desired, thelowering of the vertically adjusted gage board and for insuring on theturning of the hand wheel L2 the easy elevation, more or less asdesired, of the gage board.

In the operation and utilization of the improved mechanism described,the sheets cut from the continuous web are advancedby the feed tapesover and forwardly beyond the gage board B and onto the normallystationary support constituted by the upper course of the conveyer D.The attendant squares the sheets with their rear ends edgewise againstthe transverse gage board and with their rear sides edgewise along theback longitudinal gage board E. As the pile grows in height, the gageboard B is elevated through the turning of the hand wheel L2,- theroll-rounding forward portions of the tapes the tape rollcZ and theyieldable rollers o being bodily carried thereby and movable in unisontherewith so that the relations of the tapes and rolls to the gage boardare invariable. After the pile or stack of sheets has become quite high,the gage board E having, from time to time, been elevated step by step,the conveyer is operated manually by turning the crank handle at theforward end of the machine to move the high and heavy pile away from theposition on the conveyer' at which it had been built up so that theoperation of further stacking or pile building against the gages neednot be at all interrupted for the removal of the already made pile to adifferent place.

It isa matter of considerable convenience and saving of time to have onemade pile on the forward portion of the support and conveyer D whileanother pile is being formed on the rear of the conveyer, inassheetsinto ream lots may do so' from the transferred pile, the only shiftingbeing of the counted lots from off the pile to the proper place ofoccupancy therefor.

I claim l. In a machine. of the character described, in combination, aframe, horizontal rotatable shafts mounted transversely on said frame atthe rear and forward portions of 'much as the person having to count thethe latter, having toothed wheels thereon,V y

mounted above and transversely relatively to the rear upper portion ofthe conveyer, means for imparting an elevating adjustment to thetransverse lgage-board, and means for feeding sheets over the transversegage board onto the portion of the conveyer adjacent thereto, comprisingendless feed tapes and sets of rollers therefor, the rollers for theadvanced portions of the feed tapes being supported by, and bodilymovable` with, the transverse gage board, and yieldable rollers, aboveand coacting with said advanced tape-rollers, and bodily supported lyaid movable vrelatively to the said gage oar 2. In a machine of thecharacter described, i

in combination, a frame, horizontal rotatable shafts mountedtransversely'on said frame. at the rear and forward portions of thelatter, having toothed wheels thereon,

an endless support and conveyer consisting of articulated transverseslats having engagements around said wheels, the upper course of whichconstitutes a table,.means for manually rotating one of the`wheel-carrying shafts, a longitudinally ranging gageboard on said frameand upstanding above a rear portion of the upper course of the jointedslat conveyor, a gage-board movably mounted above and transverselyrelatively to the rear upper portion of the conveyer, having bracketsextended therefrom, vertical rods supported by the frame With which saidbrackets have guiding engagements, a pair of shafts one above, and theother below, the transverse gage-board, having pairs of sprocket Wheelsthereon, sprocket chains around the sprocket Wheels, for- Wardly locatedvertical courses of Which have connections with said brackets, means formanually rotating one of said shafts, and means for feeding sheets overthe trans- 15 verse gage-board onto the portion of the said conveyeradjacent thereto.
